The leak is caused by the fact that\nrelease_resource() merely removes the resource from the tree but does\nnot free its memory. We need to call release_mem_region() instead,\nwhich does free the memory. As a nice side effect, this brings back\nsome symmetry between the legacy and MMIO paths.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/8ad59b397f86a4d8014966fdc0552095a0c4fb2b","https://git.kernel.org/stable/c/a3263e4cf8265f0c9eb0ed8a9b50f132c7a42e19","https://git.kernel.org/stable/c/d2bf1a6480e8d44658a8ac3bdcec081238873212"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49653","score":0.00281,"percentile":0.2066,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
